sata_sil24: fix kernel panic on ARM caused by unaligned access in sata_sil24
ahci: add pci quirk for JMB362
sata_via: explain the magic fix -
Commit 96d60303fd (ahci: Turn off DMA engines when there's no device)
implemented stopping DMA engines on empty ports but it used single
sampling of status registers to determine device presence which led to
disabling of DMA engines on occupied ports. Do it after all EH
actions are complete using device presence state determined by EH.
This avoids spurious disabling of DMA engines and simplifies the code.Signed-off-by: Tejun Heo

The sata_sil24 driver has six 16-bit registers that are initialised with

This reverts commit 962400e8fd29981a7b166e463dd143b6ac6a3e76, which was
entirely bogus.The code used to multiply the character offset by "vc->vc_cols", and
that's actually correct, because 'd' itself is an 'unsigned short'. So
the pointer arithmetic already takes the size of a VGA character into
account. Changing it to use vc_size_row (which is just "vc_cols"
shifted up to take the size of the character into account) ends up
multiplying with the VGA character size twice.This got reported as bugs for various other subsystems, because what it
actually results in is writing the 16-bit vc_video_erase_char pattern
(usually 0x0720: 0x07 is the default attribute, 0x20 is ASCII space)
into some random other allocation.So Markus ended up reporting this as a ext4 bug, while to Torsten Kaiser
it looked like a problem with KMS or libata. Jeff Chua saw it in
different places.And finally - Justin Mattock had slab poisoning enabled, and saw it as a
slab poison overwritten. And bisected and reverted this to verify the
buggy commit.Reported-by: Markus Trippelsdorf

Cursors need to be in the GTT domain when being accessed by the GPU.
Previously this was a fortuitous byproduct of userspace using pwrite()
to upload the image data into the cursor. The redundant clflush was
removed in commit 9b8c4a and so the image was no longer being flushed
out of the caches into main memory. One could also devise a scenario
where the cursor was rendered by the GPU, prior to being attached as the
cursor, resulting in similar corruption due to the missing MI_FLUSH.Fixes:
Bug 28335 - Cursor corruption caused by commit 9b8c4a0b21

Remove a BUG_ON for when interrupts are disabled during an MMC request.
During boot, interrupts can be disabled when a request is made, causing
this bug to be triggered. In reality, there's no reason this should halt
the kernel, as the driver has proved reliable in spite of disabled
interrupts, and additionally, there's nothing in this code that would
require interrupts to be enabled.The only setup I've managed to make it trigger on is on the HTC Herald
during bootup when the driver is built into the kernel (mostly because
that's all I have). I believe it's related to the fact that on bootup I
get many timeout errors on "CMD5" while initializing the card. Each CMD5
timeout triggers that bug (I changed it to a WARN_ON to get it to boot in)
due to the fact that part of the timeout code involves sending the request
again. With interrupts turned off, that BUG would be triggered.Signed-off-by: Cory Maccarrone
